Confidence: I'm as sure as I can be.
Notes: It seems late in the year for Andrena, and the abdomen too broad for Lasioglossum. I didn’t get a good enough image of the wing veins to see if the marginal cell was that characteristic of honey bees. The bee’s appearance is quite different from the honey bee of a previous post* but am not excluding a dark form of Apis mellifera. The tongue looks quite long.
